ATLANTA (WXIA) -- Officials in Chicago confirmed Thursday morning that DeKalb County Police Chief Dr. Cedric Alexander is one of three finalists for the open police superintendent position in the nation's third largest city.

An investigation by the DeKalb County District Attorney's Office determined that the shooting was justified. The investigation included reviews by the Georgia Bureau of Investigation and an outside expert with more than 30 years of law enforcement experience, acccording to DeKalb County District Attorney's Office spokesperson Marcus Garner.

Benjamin's family had asked the district attorney to file criminal charges against the officer.

DEKALB COUNTY, Ga. -- Water leaking from a tower in DeKalb County began spilling into yards on Wednesday.

The leak happened at a water tower on Mason Mill Road near Clairmont Road. County spokesperson Shiera Campbell said a computer malfunction between the large tank and the main water facility led to the leak.

"When it lost communication, it didn't have anything to tell it to stop flowing, and it started to overflow," said Campbell.

Perez, 29, was shot three times at an apartment off Shallowford Road, outside Atlanta. Mondragon shot a second man twice.

Mondragon then fled to Texas and changed his name. But in 2014, he was arrested on driving while intoxicated charges, and police fingerprinting revealed that he was wanted on murder charges in DeKalb County.

The surviving victim and a man who drove Mondragon to the scene of the shooting both testified for the prosecution in the trial.

After closing statements, a jury deliberated for over 2 hours before delivering guilty verdicts on all counts.
